"I would say in an hour and a half's time I got 6 inches of rain," said Borrego Springs resident Virginia Perrine.

While crews cleared mud and debris from State Route 78, Perrine took matters into her own hands on Yaqui Pass Road.

She walked and talked while picking up sticks and kicking large rocks to the side of the road.

"I just hate to run into this with the car," she said.
